Mozilla Solo review (2026): an honest verdict on the AI website builder now shutting down November 30, 2026. Scores, pricing, pros, cons, and alternatives.
Solo was a genuinely good idea executed cleanly: type a few prompts and an AI stands up a decent one-page site for a solopreneur, hosting and a domain included. But the only verdict that matters in 2026 is that Mozilla is shutting it down — sites and data are deleted November 30, 2026. That makes it un-recommendable to start on today, no matter how pleasant the builder is. The scores below rate the product as it was; the longevity score is the one that decides it.
Reviewing Mozilla Solo in late 2026 is unusual, because the headline fact overrides everything else: it is being discontinued. Mozilla has said all Solo sites and data will be deleted on November 30, 2026, with no recovery afterward. So this is less "should you buy it" than "what was it, what was it good at, and where should a Solo user go now."
I will still score it honestly on the merits, because a lot of people built real sites on Solo and deserve a fair accounting of what they had. I also run a competing product, Kompozy — but Kompozy is not a website builder, so there is no rivalry to color the scores here. That actually makes this review cleaner: I can praise what Solo did well without it being a threat to anything I make.
Everything below reflects Solo as of 2026-10-02, drawn from Mozilla's own materials and Solo's support documentation. Where Solo did not publish a figure, I say so rather than guess. The one number that is not in dispute is the deletion date, and it is the reason the overall score is what it is.
Solo (soloist.ai) is an AI website builder that Mozilla launched out of its innovation group for solopreneurs — coaches, consultants, trades, small service businesses. You answer a few prompts about your business and Solo generates a professional-looking site: layout, copy, images, and a structure, with hosting and a custom domain bundled in. The pitch was that a non-technical person could be online in minutes without touching a template editor or a hosting dashboard. It went to beta in late 2023 and reached a 1.0 release in 2024, by which point Mozilla reported thousands of published sites. It offered a free tier plus paid Solo Pro and Grow plans that added things like extra custom domains, custom code, and higher image limits. As an AI-first builder it leaned on generation rather than drag-and-drop: the AI did the first pass and you edited from there. It was web-based, with no native mobile app. In short, it was a fast on-ramp to a simple professional presence — and that on-ramp is closing.
As of this review, Solo is for no one starting fresh — do not build a new site on a product that deletes everything on November 30, 2026. The honest audience for this page is existing Solo users who need to understand what they had and plan their exit: export the HTML, download every image from the CSV, transfer any Solo-registered domain, and re-host elsewhere. Historically Solo fit the non-technical solopreneur who wanted a clean one-page presence without learning a builder — and for that narrow job it was pleasant. That profile should now look at a living AI builder for the site, and treat the ongoing marketing content as a separate need.
| Dimension | Score | Why |
|---|---|---|
| Ease of use & onboarding | 4.1 / 5 | Answer a few prompts, get a site — genuinely approachable for non-technical users, which was the whole point. |
| AI site generation quality | 3.6 / 5 | Solid first-pass layouts and copy for a simple one-page presence; not a design tool for complex, multi-section sites. |
| Templates & design range | 3.3 / 5 | Clean and modern but limited in range; fine for a brochure site, thin if you want distinctive design. |
| Hosting & custom domain (bundled) | 3.9 / 5 | Including hosting and a domain in one flow was a real convenience and a genuine differentiator while it lasted. |
| Editing & flexibility | 3.0 / 5 | AI-first with manual edits on top; paid tiers added custom code, but it was never a deep, extensible platform. |
| Pricing & value | 3.4 / 5 | Free tier plus Pro and Grow was reasonable for what it did — undercut by the fact the paid plans are now being refunded and wound down. |
| Data portability & exit | 2.6 / 5 | An HTML export plus a CSV of image links is a usable snapshot, but images download one by one and the result is static, not a living site. |
| Availability & longevity | 1.0 / 5 | Being deleted on November 30, 2026. This is the decisive mark — a discontinued product cannot be recommended to adopt. |
| Support & communication | 3.2 / 5 | The shutdown was documented with export steps, a refund policy, and a domain-transfer path — a reasonably clean wind-down, if an unwelcome one. |
Solo ran a free tier alongside paid Solo Pro (around $20/month) and Grow (around $85/month) plans, with annual billing discounts; the paid tiers unlocked more custom domains, custom code, and higher image allowances. For the job it did, that was fair pricing — a free way to get online, and modest paid steps for people who needed more.
The pricing conversation in 2026 is moot, though, because the plans are being wound down. Mozilla says active Pro and Grow subscribers get a prorated refund for unused time, calculated as of October 1, 2026, returned automatically to the original payment method. So the practical "pricing" advice is the opposite of a buying guide: if you are a paid subscriber, confirm your refund lands; if you are on free, there is nothing to pay and nothing to renew.
Judged on value, Solo was reasonably priced for a simple AI site builder. Judged on 2026 reality, the value is zero going forward, because you cannot keep the product. That is not a knock on how it was priced — it is the consequence of discontinuation, and it is why the value score sits where it does rather than higher.
| Use case | Fit | Why |
|---|---|---|
| Starting a brand-new website today | Weak | Do not build on a product scheduled for deletion on November 30, 2026. |
| Existing Solo users planning an orderly exit | OK | The export, refund, and domain-transfer paths are documented and workable, even if the export is static. |
| A non-technical solopreneur who wants a simple site fast | Weak | The job Solo did well, but it is closing — take that need to a living AI builder instead. |
| A complex, multi-section, or highly custom site | Weak | Never Solo's strength; it was built for simple one-page presences. |
| Preserving the content of a site you already built on Solo | OK | The HTML + CSV export captures your content, provided you download every image before the deadline. |
| Ongoing marketing content and multi-platform publishing | Weak | Solo never did this — it generated a site once and stopped; this is a separate category of tool. |
Let me be precise so this is not mistaken for a pitch: Kompozy is not a Solo replacement. It does not build or host a website, and if your need is "I lost my site, give me a new one," the honest answer is a living website builder or a static host for your HTML export — not Kompozy.
Where the two relate is the thing Solo never did. Solo was a launch tool: it got you online once, then stopped. It had no ongoing content engine, no clipping, no social posting — a site that sat there until you updated it by hand. Kompozy is the opposite shape: it generates finished, on-brand content continuously — persona and avatar video, clips, carousels, quote cards, blogs, and newsletters — and publishes it across nine platforms on autopilot through a per-post review pipeline. For the solopreneur who liked Solo because it did the work they did not want to do, that ongoing engine is a closer match to the original appeal than any static snapshot. Pair a real website builder for the site with Kompozy for everything that drives traffic to it.
Yes. Mozilla has said all Solo websites and data will be deleted on November 30, 2026, with no recovery after that date. You should export your site and move any purchased domain before the deadline.
Not for a new site. As pleasant as the builder was, it is being discontinued, so starting anything on it now means building on a product that will be deleted on November 30, 2026. Existing users should focus on exporting and migrating.
In Account Settings, use "Download Website Data." You get a ZIP with an HTML export plus a CSV of links to your images. The images are not in the ZIP — download each one from the CSV before November 30, 2026, or they are deleted with everything else.
Mozilla says active Pro and Grow subscribers receive a prorated refund for unused time, calculated as of October 1, 2026, returned automatically to the original payment method.
Domains registered through Solo need to be transferred before the service closes — Mozilla points users to Name.com, with a separate path for domains originally bought through IONOS. Start the transfer early so you do not lose the address.
For the website itself, a living AI builder such as Framer, Durable, Wix, or Hostinger's AI builder, or Carrd for a simple one-pager; you can also re-host your HTML export on a static host like Netlify or Cloudflare Pages. For the ongoing marketing content Solo never produced, a generation-and-publishing engine like Kompozy covers that separate need.
No — Kompozy is not a website builder and does not host sites. It handles the other half of a solo business's online presence: generating and publishing content across social, blog, and email. Use a real site builder for the site and Kompozy for what brings people to it.
